It depends on the specific ion and its electrochemical gradient.

Vedclass · Answer

(D) The reversal potential,also known as the equilibrium potential,is the membrane potential at which there is no net flow of a particular ion across the membrane.
For a single ion species,the reversal potential is determined by the Nernst equation.
Depending on the concentration gradient and the charge of the ion,the reversal potential can be positive (e.g.,for $Na^+$) or negative (e.g.,for $K^+$).
Therefore,the reversal potential is not fixed as always positive,negative,or neutral; it depends on the specific ion and its electrochemical gradient.
